Available for all GM transmissions

Have you ever experienced opening your hood and seeing an oily mess under the passenger's side rear of the engine compartment because your automatic transmission dipstick has vibrated loose? If you have had this happen or you don't want this scenario to happen to you, OPGI has the solution with our locking dipsticks. They're available for all the GM automatic transmissions and come with a gold iridite tube and the locking dipstick.
